I have to point out that at $63 per crude barrel, the cost of oil accounts for $1.50 of the $28 to $38 per gallon of motor oil. Okay the value of the motor oil that's in crude might be relatively higher, but even in crude oil prices go up 50% it would probably add $1 per gallon the the price of motor oil.
I assume the rest of the cost is additional refining, additives, marketing, bottling, transportation, R&D etc.
